Definitions
- the present invention is directed to highlight color display architecture using enhanced dark state.
- each pixel has two sub-pixels and the two sub-pixels are based on two display cells capable of displaying black and white color states and only one of the sub-pixels has a color filter overlaid on top of a display cell.
- a color state e.g., red, green or blue
- the sub-pixel with the color filter is turned on and the sub-pixel without a color filter is turned to the white or black state.
- the black state is desired, both sub-pixels are turned to the black state.
- the sub-pixel without a color filter is turned white and the sub-pixel with a color filter is turned black.
- the disadvantage of such a technique is that the maximum reflectivity of the white state is only 50% since the sub-pixel with the color filter must be turned black for that state. Conversely the color state is of a dark shade (with the black turned on) or a light shade (with the white turned on).
- the present invention is directed to an alternative design of a highlight color display.
- One of the key features of the invention is the intense color of the display fluid filled in the microcups, which allows the dark state to appear black.
- the advantage is that no sub-pixel architecture is required in the active matrix array or the microcup structure. Only one display fluid is needed for all microcups. Furthermore, there is no alignment required between the pixel electrodes and the microcups. In practice, a standard active matrix array may be used to drive the display device.
- One aspect of the invention is directed to a color display device, which comprises a plurality of microcups wherein
- the color display further comprises an adhesive layer of a dark color or a color complementary to the color of the solvent.
- the top surface of the partition walls is of a dark color or a color complementary to the color of the solvent.
- the partition walls are of a black or dark color. In one embodiment, no more than 10%, preferably no more than 3%, of the light is reflected at the peak transmission of the dark color state.
- the dark color of the solvent is dark red, dark green or dark blue.
- the reflectance of the medium color state achieved by driving the white charged pigment particles to an area between the common electrode and the pixel electrode in the microcup has at least five times, preferably at least ten times, the reflectance of the dark color state.
- the microcups and the pixel electrodes are aligned.
- the microcups and the pixel electrodes are un-aligned.
- the medium color state is achieved by driving the white pigment particles to an area between the common electrode and the pixel electrode.
- the particles are distributed throughout the display fluid.
- the particles are driven to be at the mid-level in the microcup.
- each microcup represents a pixel.
- the device further comprises an active matrix driving system.
- Another aspect of the invention is directed to a color display device, which comprises a plurality of microcups wherein
- the colored solvent is red, green or blue respectively.
- the microcups and the pixel electrodes are aligned. In another embodiment, the microcups and the pixel electrodes are un-aligned.
- the color state is achieved by driving both the white and black charged pigment particles to an area between the common electrode and the pixel electrode. In one embodiment, the particles are distributed throughout the display fluid. In another embodiment, the particles are driven to be at the mid-level in the microcup. In one embodiment, the color state achieved by driving both the white and black charged pigment particles to an area between the common electrode and the pixel electrode has a reflectance at least five times, preferably at least ten times, the reflectance of the black state. In one embodiment, each microcup represents a pixel. In one embodiment, the device further comprises an active matrix driving system.

- a microcup ( 100 ) is sandwiched between a first layer ( 101 ) and a second layer ( 102 ).
- the microcup ( 100 ) is surrounded by partition walls ( 107 ).
- the first layer comprises a common electrode ( 103 ).
- the second layer comprises multiple pixel electrodes ( 104 ).
- the microcup ( 100 ) is a micro-container filled with a display fluid ( 105 ). Details of the term “microcup” are given in U.S. Pat. No. 6,930,818, the content of which is incorporated herein by reference in its entirety.
- microcups are specifically mentioned in the present application, it is understood that any micro-containers (e.g., microcapsules), regardless of their shapes or sizes, are within the scope of the present application, as long as the micro-containers are filled with a display fluid and have the same functions as the microcups.
- micro-containers e.g., microcapsules
- the display fluid ( 105 ) is an electrophoretic fluid comprising only one type of charged pigment particles ( 106 ), usually white, dispersed in a colored dielectric solvent or solvent mixture, as shown in FIG. 1 a .

- the display device may also have an adhesive layer ( 108 ) at the opposite side of the viewing side.
- the adhesive layer is colored and the first layer, the second layer and the partition walls ( 107 ) are all transparent.
- the purpose of the colored adhesive layer is to balance the color of the dark color state or enhance the black state.
- the adhesive layer may be of the black color or a dark color complementary to the color of the display fluid. In the latter case, if the microcups are filled with a display fluid of a dark red color, the dark color state will have a tinge of red. In this case, the adhesive layer may be of a combined color of dark green and dark blue. The dark green and dark blue colors from the adhesive layer through the partition walls and the red color from the display fluid together will provide a neutral dark color.
- the adhesive layer then may be of a combined color of dark red and dark blue (complementary color). If the microcups are filled with a display fluid of a dark blue color, the adhesive layer then may be of a combined color of dark red and dark green (complementary color). As shown, the adhesive layer has the function of enhancing the dark color state displayed by the display device. Suitable pigments or dyes are added to the adhesive layer to achieve the desired color of the adhesive layer.

- the second layer ( 102 ) comprises multiple pixel electrodes ( 104 ). However, the pixel electrodes and the microcups may be aligned (see FIG. 1 a ). In an aligned design, each pixel electrode corresponds to one microcup.
- FIG. 2 a shows an un-aligned design.
- the term “un-aligned” or “non-aligned”, in the context of this invention, is intended to mean that at least one pixel electrode ( 104 ) is permitted to be underneath more than one microcup, as shown in the figure.
- FIG. 2 b is a top view of an un-aligned design.
- the microcups (solid lined, 100 ) and the pixel electrodes (dotted lined, 104 ) are un-aligned in only one direction and each pixel electrode is underneath two neighboring microcups.
- FIG. 2 c is a top view of another un-aligned design.
- the microcups (solid lined, 100 ) and the pixel electrodes (dotted lined, 104 ) are un-aligned in both directions and each pixel electrode is underneath four neighboring microcups.

- the display fluid is of the same color in all microcups.
- the white particles move to be near or at the pixel electrode ( 304 b ). Because the blue dye absorption is strong, the color seen in this case is a very dark blue color. At a high enough level of the blue density, such a pixel will appear black to the viewers. As described previously, if the fluid is not dark enough, the color will appear black if the fluid color is balanced by the complementary colors in the adhesive layer 108 .
- the particles when the particles are driven to an area between the common electrode and the pixel electrode, the particles may be distributed throughout the display fluid or a substantial amount of the particles may gather at the mid-level in a microcup.
